The sustainability of a mineral resource depends, among other aspects, on what the mineral in question will be used for, price fluctuations, future resource requirements, and downstream manufacturing. A balance must be struck between the long-term commitment of developing a mineral deposit against the short-term threats of a changing commercial and social environment. Long-term resource ...

Beneficiation is a pervasive policy paradigm in South Africa. This is partly because it seems to be a logical and natural progression for countries like South Africa to develop by moving from exporting raw natural resources, particularly minerals, to capturing more of the value added and engaging in greater downstream processing. It is also ...

In this paper, electrostatic beneficiation of a lunar simulant at 1/6 g, as run on reduced gravity flights (RGFs), is reported. Enrichment of the target mineral ilmenite was achieved as high as 65 and 106% in the two RGF flights undertaken, showing that tribocharged electrostatic beneficiation is a viable process in the lunar environment.
